I would say that UFOs are not round; we tend to think of them that way because the first descriptions of them called them "flying saucers". But ask any logistics manager how to stack goods then "cover your ears" to listen to his response to a round storeroom. You might also ask the crew what they thought about cheese shaped cabins.
A round shape does not give any aerodynamic advantage; on the contrary, you would have to have some way of controlling every surface for steering. A triangular- delta-shape would in the end run be most efficient. As for "stacking" in the mother ship, round is the worst possible shape in terms of space/volume.
OK, where is the Mother Ship? We have thousands of satellites between us and the moon, and some even more further out. Well, we know about stealth technology, we even use it on the B2 (when it isn't raining), so we must assume that in all bands of observation: visual, UV, radar (all ranges), IR, etc, these things outwit us; including the launch of small flying saucers through the vast network of radar surveillance all countries seem to have these days. What good is it selling a missile defence system to Poland if UFOs zip right through it?
So, I don't think UFOs are round. I would love to believe in them, but until they land, like Cortez in Mexico, or Pizzaro in Peru, I will have to rest with just the pleasant, Science Fiction dreams of my youth.
no
Where humans and alcohol are, UFOs will be.
the correct answer is UFOs thanks for asking
There have been reports of sightings of white UFOs.
The ones who study UFOs are called Ufologist. They study every thing about unidentified flying objects (UFOs).
Please check the related links for information about UFOs.
UFOs can go as high as your imagination allows.
Since UFOs are unidentified, it is unknown what is inside of them.
No, UFOs are not technically extinct, they are just rare to see.
The African Origins of UFOs was created in 2006.
People have reported sightings of UFOs in France, but there is no proof of their existence.
Like flying machines on Earth, UFOs are equipted with landing gear.
